SPECIFICATION forming part o f Letters Patent No.y 278.7914, dated June5, 1,883.

Application filed October 1G, 1882. (No model.)

To all whom t may concern:

Beit known that I, CLAUDE HME, of Bay City, in the county of Bay andState of Michigan, have invented new and useful Improvements inSalt-Grainers; and l do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawing, which forms a part of this specification.

The nature of this invention relates to certain new and usefulimprovements in devices for the manufacture of salt by steam-evaporationin what are ordinarily termed salt-grainers, by means of whichthe salt,as fast as precipitated, is automatically removed from the grainer, andthe brine is agitated by the devices employed for so removing the salt,such agitation greatly facilitating the process of precipitation.

rlhe invention consists in the peculiar construction, combination, andoperation of parts, as more fully hereinafter set forth.

ln the accompanying drawing7 which forms a part of this specification,my invention i shown as applied to a grainer.

A represents a grainer of the ordinary construction, except ashereinafter described, the `licor of which, at the discharge end,terminates in an upwardly-inclined plane. Uponeach inner side wall ofthe grainer there is seciued, in the usual way and above t-he level ofthe brine, a rail, B, upon the top of which travel the carrying-bars C,which are each made in two parts, which are jointed together, as shownat a. Secured to each of these bars, and coincident upon the oppositesides, are the hanging supports D, the lower ends of which nearlyapproach the iloor of the grainer. To the front of each pair of thesebars is pivotally secured the hoes e, the length of which corresponds tothe width of the floor of the grainer. These hoes are so attached to thependent arms that in the forward reciprocation toward the inclined endof the grainer the hoes will be in a vertical position, resting againstthe front faces of their supports, and with their lower edges upon, ornearly so, the bottom of the grainer. l'n the reverse motion of thetravel resistance of the brine will cause these hoes to assume ahorizontal position until its portion of the travelis completed.

The object of jointing the carrying-bars C,

as described, is to enable the-front hoe to travel up the inclined planex and force the salt over the front end of the grainer in the travel ofthe hoes.

F are a -pair of sprocket-wheels, one being secured near each end of theshaft G, the ends ofthe shaft being suitably journaled in boxes upon theopposite sides of the grainer, and to one of the projecting ends of thisshaft, by means of a crank orV pulley, motion is imparted.

H are two grooved pulleys, although these latter may be sproclet-wheels,if preferred, secured upon the shaft I, journaled as described withreference to the shaft G. v

J are sprocket chains running over the sprocket-wheels and pulleys-oneupon each side ofthe grainerand each one'of these chains has projectingon either side and coincident in both chains a small stud, I), upon eachof which is placeda small roller. In the rotation of thesesprocketwheels and chains these frictionwheels upon the studs b come in contactwith the forks cupon the ends ofthe rodsd, the opposite ends of whichare secured to the risers K, the lower ends of which are rigidly securedto the carryingwbars, so that in the rotation of the chains the hoeswill lic-withdrawn to the rearend of the grainer. In the furtherrotation of the chains these small studs b, with their wheels, willengage with projections o on the carrying-bars and force the hoes towardthe front end ofthe grainer, carrying the deposited salt with them.

In order to prevent any uncertainty in this description, the front endof the grainer is that one wherein the iloor terminates in theupwardly-inclined plane. The upper edges of these hoes terminate inteeth f, which project to the surface of the brine, andthe intervalsbetween the teeth in each of the hoes being coincident, they pass intheir travel between the steam pipes-such as are usually found ingrainers-so that when the hoes are in the act of withdrawing the salttheir projecting teeth act as agitators of the surface ofthe brine. Thefront hoe and its connections differ from the othersin the series. Thishoe is pivotedto a bar, D', which is provided with a friction roller, m,and is secured to the short arm of the carrying-frame C in front of thepivot a. The roller m rides up a track, M, of the same IOO incline asthe front end of the grainer, and thus allows this front hoe to take thesalt from the succeeding hoes and force it over the end of the grainer.

I am aware of Patent N o. 267 ,085, issued to e described, forimparting,` to said hoes a reciprocating motion, whereby the salt isforced in one direction automatically, and the ngers f automaticallyagitato the brine to assist granulation, as specied.

2. The front hoe, e, and support D', having roller m, combined with thejointed carryingframe C a, rail M, and incline as and for the purposeset forth. p

3. The sprocket -wheels F H 'and endless chains J, having,` studs b,provided with friction-wheels, combined with the carryingframe C, risersK, and rod having forked end c, as and for the purposes specied.
